Newton's Laws of Motion

Interactive Virtual Simulators

Law of Inertia

An object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Initial Velocity:0.00 px/frame

Applied Force:0 N

Final Velocity:0.00 px/frame

A continuous force from the spacecraft's engine will cause it to accelerate. A larger mass requires more force for the same acceleration.

Spacecraft Mass (1000 kg)

Engine Thrust (2000 N)

Initial Velocity:0.00 m/s

Applied Force:2000 N

Acceleration:2.00 m/s²

Final Velocity:0.00 m/s

When two spacecraft modules separate (in static), the force pushing them apart results in equal and opposite momentum changes.

Module 1 Mass (1000 kg)

Module 2 Mass (800 kg)

Module 1 Velocity: 0.00 m/s

Module 2 Velocity: 0.00 m/s
